Presentation of High Strain-Rates on Deformation Mechanism Maps.

摘要

Phonon drag, power-law breakdown and the condition for adiabatic shear are expressed in terms of material properties, a critical strain-rate, and a critical strain. This information is incorporated into the construction of deformation-mechanism maps, which then show a field of drag-controlled plasticity and one of adiabatic shear (in which unstable flow may occur), together with the more usual fields of stable plasticity, power-law creep, diffusional flow and so forth. Where possible, the results have been compared with, and matched to, experiments.
